I was scrolling through Google photos when I noticed they had auto-categorized some of my pictures. Overall I have to say their algorithm was not too bad. It was able to recognize (from left to right) a watermelon, a microscope picture of a strawberry and a microscope picture of homemade bread. Taken with my smartphone microscope of course.

It trips up a bit when it gets to what the majority of my photos contain ... bike horns. These particular images show me digitally marking up an early 3D printed horn prototype to communicate design changes to Chris, the industrial designer for Loud Bicycle.

The basic idea in this paper is an experimental extension of previous results. In the previous paper, we demonstrated in simulation how electromagnetic fields are spectrally and spatially split into different regions of a metamaterial structure. In this paper we report how we measured this field splitting:

We also demonstrated how this method might be expanded to include three different, distinct absorption frequencies.
